class_docstr: Creates a new data transfer configuration.
  
  .. seealso::
      For more information on how to use this operator, take a look at the guide:
      :ref:`howto/operator:BigQueryCreateDataTransferOperator`
  
  :param transfer_config: Data transfer configuration to create.
  :param project_id: The BigQuery project id where the transfer configuration should be
          created. If set to None or missing, the default project_id from the Google Cloud connection
          is used.
  :param location: BigQuery Transfer Service location for regional transfers.
  :param authorization_code: authorization code to use with this transfer configuration.
      This is required if new credentials are needed.
  :param retry: A retry object used to retry requests. If `None` is
      specified, requests will not be retried.
  :param timeout: The amount of time, in seconds, to wait for the request to
      complete. Note that if retry is specified, the timeout applies to each individual
      attempt.
  :param metadata: Additional metadata that is provided to the method.
  :param gcp_conn_id: The connection ID used to connect to Google Cloud.
  :param impersonation_chain: Optional service account to impersonate using short-term
      credentials, or chained list of accounts required to get the access_token
      of the last account in the list, which will be impersonated in the request.
      If set as a string, the account must grant the originating account
      the Service Account Token Creator IAM role.
      If set as a sequence, the identities from the list must grant
      Service Account Token Creator IAM role to the directly preceding identity, with first
      account from the list granting this role to the originating account (templated).
